Summary:A phase-locked electric drive is widely used in thermal imaging and laser scanning systems due to its high accuracy characteristics in a wide range of angular velocity control. The aim of the work is to develop ways to control the electric drive with improved dynamic performance. The issues of building an electric drive with advanced unlocking of a logical comparison device into phase comparison mode, which ensures that the electric drive is switched to closed-loop control with a decrease in the angular velocity error to a predetermined value, are considered. A method of a time quasi-optimal control of the electric drive, which makes it possible to improve the dynamic characteristics of the electric drive in transient synchronization modes, is proposed.
